Would you please try copying /usr/lib/hadoop/client/htrace-core4.jar to $GEOSERVER_HOME/webapps/geoserver/WEB-INF/lib and restarting GeoServer?

Also, the Cloudera 5.7 VM that I downloaded runs Java 7. Did you modify the HBase tutorial POM to target Java 7 or did you set up Java 8 on the VM?

I'm setting up GeoMesa HBase on Cloudera 5.7 to see if I can replicate your issue. I had set up Hadoop + HBase "by hand" rather than using Cloudera when I prepared and tested the HBase tutorial, and I probably made some assumptions in configuration that are not valid for your setup.

In the meantime, one issue that you might want to check is this-- unfortunately, the HBase GeoServer bundle (geomesa-hbase-gs-plugin-1.2.2-install.tar.gz) included in GeoMesa 1.2.2 is broken due to a missing dependency. This was fixed shortly after release (https://github.com/locationtech/geomesa/commit/65d9b1c2e3b25a19d086863faf4ad04718d039f5), so you might want to try building the master branch of GeoMesa (1.2.3-SNAPSNOT) or and installing the plugin bundle instead. I am not sure if that's your issue, because you would get a lengthy stack trace in the GeoServer log, but it's worth checking.

vGeoServer= 2.9 RC1

So GeoServer is installed on the Cloudera VM? Which version of GeoServer are you using? GeoMesa currently requires GeoServer 2.8.1, which was not made clear in the HBase tutorial (apologies for that).

Re: the SSH github link: The link is correct, but your are absolutely right that using the SSH link with Github requires some additional steps, which can be avoided by using the HTTPS link instead. We will update our tutorial documentation to use those links instead. Thank you!

We are testing Geoserver/Geomesa in a Virtual Machine of Cloudera (Cloudera CHD Oficial Image) ('all in one node'), in a previous step to production System (Cloudera Also)

Cloudera v5 do NOT use HADOOP_HOME or HADOOP_FREFIX (I chequed it in Dev & Production System) (IF you are using Parcels)

Only Exits: HADOOP_CLASSPATH=/opt/cloudera/parcels/CDH/lib/hive/lib/*:/etc/hive/conf/

From document, I have a doubt "git clone git@github.com:geomesa/geomesa-tutorials.git"
¿Link direction Its correct? ERROR: Permission denied (publickey)

Hi Alberto,

Do you have Hadoop configured on the GeoServer node? If so, are the HADOOP_* environment variables set for the user running Tomcat?

I'll try and work with Matt tomorrow or the next day to document a few more details.

Thanks,

Jim

- Use GeoServer from Binary Distribution

- Use Cloudera QuickStart 5.7:

    HBase 1.2.0
    hbase.rootdir=hdfs://quickstart.cloudera:8020/hbase
    zookeeper.znode.parent=/hbase
    zookeeper.znode.rootserver=root-region-server
    root-region-server=root-region-server

Thanks, Alb

Are you using the embedded Jetty in the GeoServer binary distribution, or are you running the GeoServer WAR in another server (Tomcat, JBoss/Wildfly, etc.)?

Also, how is your HBase configured? Can you show us the contents of your hbase-site.xml?

Hi

I'm going this:
https://github.com/geomesa/geomesa-tutorials/tree/master/geomesa-quickstart-hbase

Install GeoMesa, OK

Run the tutorial, OK (I see two tables in HBase 'geosmesa', and 'QuickStart_z3' )

Instal GeoServer, OK

Load JAR into geoserver, OK

But: I cant connect with HBase Store:

"New Data Sources" > HBase (GeoMesa) > bigTable.table.name=geomesa
"Error message: java.lang.reflect.InvocationTargetException"

I think the problem, is connection to HBase / Can't find "hbase-site.xml"

Then, I copied it to (and restart):

./resources/hbase-site.xml
./webapps/geoserver/WEB-INF/classes/hbase-site.xml
./webapps/geoserver/WEB-INF/hbase-site.xml
./webapps/geoserver/hbase-site.xml
./webapps/hbase-site.xml
./hbase-site.xml

In the log: "WARN [data.store] - Error obtaining new data store"

Why cant find hbase-site.xml?? Is this my problem?

BR, Alberto
